SHAFT-BEARING.'

Patented Maren 19, 1907.

Application filed Iloveniber 2, 1906. Serial No. (141.800.l

l* y Be it known thatl, J .icon F. Arens, residing at Kalkaska, in` the county ol Kalkaska and State of Michigan, have invented certain newand useful Improvements in Sl\ar'1;Bear ings,of which the following is a speciiication. I'My invention relates to certain new and useful improvements in shaft-bearings; .and ,it more particularly relates to that class of "'iofbearings known as antifriction-bearings, andis more'specially designed for use in connection with Wind-wheel shafts suclnfor instance, as that disclosed in my copemlin;r application'v filed June'v 1, '1906,` Serial No 319384. v lGenerically, vmy invention comprises a re- `movablesleeve for the shaft end upon which suitable spacing-rings are held and `between vbioh-ring's bearing-rollers rest nella removable. sleeve-lining for the beating-box, togetl'ier With ineansffor retaining the shalt in yits bearing and means for conducting,r lubrieating-'oil to the bearing-rollers. 'y In its more detail construction my inven` ltion comprises certain novel construction., I combination, and arrangement of parts, all of whiehwill be first described. in detail and y)then be specically ,minted out in the ap;

" j pended claims, .reference being had to the ac- "3`10 'conipanying drawings, in Which-- I embodying my invention.

\ ,larged central vertical longitudinal section of a bearing. v35 line 3 3 of Fig. 2. y

g Referring'imw to the accompanying drawings,'in which like numerals and letters of reference indicate like parte in all of the iigure's, 1 designates the wind-.Wheel shaft,

4o which carries a wind-Wheel 2 and is mounted in the bearing-hubs 4 von the supports The Fig. 3 is a cross-section on the' bearings of the support 3 and their coper'.

ative connection.,with the Wind -Wheel shaft lorm my present invention, while the re- 4 5 mailling 'parts olt the windmill may be of anyy approved construction such, for instance, as shown in` my eopending application hereinbeforereferred to-sinee the remainingparts per se form no portion of my present inven- 50 tion. l

i By reference more particularly to Figs. 2 and 3 it will be seen that in my improved construction of bearing the Windmill-shaft 1 at its ends isprovided with a metallic sleeve 5.,5, 7ri1nn,ing the full length of the bearing-box 4 and secured in place by a series ol screw 5, preferably three in number.

' Surrounding the sleeve 5 and space d at suitable intervals apart :1re a series ol' collins 6, which are held .in place by screw-bolts 7, which pass through the sleeves 5 and the endsI .jl the shalt l. Surrouinlling the sleeve 5 and. between the collar-sli the bearing-roll- 'ers 8 are held wit]iinfthebearing-blor.l

The hubportieh `tof the bearing is secured tothe supports .by bolts or otherwise, as mov he iound desirable, and its bearing-face' is linediwith a sleeve 9, that is secured to the l.hub 4 by a series of screw-keys 1l), as indieated, the screw-keys 1() beingr preferably four in number and arranged'as clearly 'sh own in Figs?. 2 and 3.

It should be noticed that the collars (i are of alesser outside diameter than the internal diameter ol', the hub-sleeve 9, so as to be spaced slightly therefrom. f?

The shaft l hasits end la'threaded, is at 1h, to receive a bur 1l, which is adapted to lie close up against the end face of the hub L1. Inclosin'g the end of the hub 4 and the bur 11 is a'eap 12, which screws onto the threaded portion 4.x ol the hub 4. The hub -1 is provided With a pluralitiv of oil-ducts 4Y, which communicate with respective sets oli' bearingrollers 8, and these ducts 4*' ma;- be closed by Figure 1 1s a slde elevation ot a windmill capsflz, il desired.

Thus it will be seen that I have provided ing in which the bearing-sleeves 5 and 9, upon which the-Wear o1 the bearing comes, can be readily replaced whenever it can he lound .desirable to do so by simply unsc1' =.\ving the screw-keys that hold the respective sleeves mplace, 1t being understood, o1V course, that the rings 6 areffirst removed betere the sleeve' `5 is taken oil the shaft end.

-While l have shown and described my invention as used with windniilbshafts, yet l .a very simple and eliective antifriction-bear- IOO ` locking said sleeve and shaft together, spaced rings mounted on said sleeve, bearing-rollers mounted between said rings, a fixed member having .a bearing-aperture', a sleeve lining ,5 ,Said bearing-aperture, and screw-keys con fnecting said last-named sleeve to said bearin member, and said bearing-rollers being hel between said sleeves, substantially as shown and described.
